How to fill out Combine Datasets using Inexact Character Variables in SAS®

1. Identify the datasets you want to combine.
2. Determine the character variables that have inexact matches between the datasets.
3. Standardize the character variables to ensure consistent formatting (e.g., case, spaces).
4. Use the PROC SQL statement or DATA step in SAS to perform a join on the datasets using the inexact character variables.
5. Specify the type of join (e.g., LEFT JOIN, INNER JOIN) based on your requirements.
6. Use functions such as SOUNDEX or ANYDT to handle inexact matches if necessary.
7. Preview the merged dataset to ensure that the combination is performed correctly.
8. Save the newly created dataset with a meaningful name.

Who needs Combine Datasets using Inexact Character Variables in SAS®?

1. Data analysts who need to merge datasets with inconsistent naming conventions.
2. Researchers who are working with datasets from different sources that may have variations in character variables.
3. Businesses looking to consolidate customer records from various databases that have slight differences in data entry.
4. Anyone involved in data integration projects that require a matching of records across datasets with non-exact character variables.

When combining two data sets What is meant by concatenating?

Concatenation is the combining of two or more data sets, one after the other, into a single data set. In the output data set, observations from the data set that is listed first in the SET statement are followed by observations from the data set that is listed second in the SET statement, and so on.

When appending two data sets, what happens if one data set has a unique variable name?

If the data sets you name in the SET statement contain variables with the same names and types, you can concatenate the data sets without modification. If the variable types differ, you must modify one or more of the data sets before concatenating them.

When combining two data sets, what is meant by a one-to-one merge?

Definition of One-to-One Merging In a one-to-one merge, the number of observations in the new data set is equal to the number of observations in the largest data set that you name in the MERGE statement.

How do you combine datasets with different variables in SAS?

To do this you use a MERGE statement and a BY statement within a data step, like this: DATA New-Dataset-Name (OPTIONS); MERGE Dataset-Name-1 (OPTIONS) Dataset-Name-2 (OPTIONS); BY Variable(s); RUN; You must sort both datasets on your matching variable(s) before merging them!

What data sets have two variables?

Bivariate numerical data involves two variables in a dataset. Relationship between two variables can be visualized using a scatter plot and measured using a metric called correlation coefficient.

How to convert all character variables to numeric in SAS?

To convert a character value to a number, you use the INPUT function with a specified informat, which indicates how you want SAS to read the number. The INPUT function looks like this: new_var = input(original_var, informat.); where informat is the name of the SAS informat used to interpret the value.

What is the difference between set and merge in SAS?

SET is used primarily for adding cases, but it also can be used to propagate variables across an entire file. MERGE will combine two or more files that have the same cases and different variables. It can also be used for updating values when you wish to force a change regardless of the new value.
